T0 on whom it may concern:

Be it known that 1, CHARLES L. BEERS, a citizen of the United States,and a resident of Scranton, in the county of Lackawanna, in the State ofPennsylvania, have in vented new and useful Improvements inFire-Box-Lining Supports, of which the following,taken in con-- nectionwith the accompanying drawings, is a full, clear, and exact description.

Thisinvention relates to the fire-boxes of stoves and ranges, and hasspecial reference to the devices employed for supporting the fire-bricklinings in said fire-boxes The object of the invention is to provide asupporting device which shall be simple and inexpensive in construction,adapted to be readily applied to any stove or range, and adjustable tovarying depths of fire-boxes; and to that end the invention consists inthe comwith the movable grate and fire-box lining, of plates disposed injuxtaposition to and parallel with the walls of the fire-box andprovided with ledges for supporting the firebrick lining, said ledgesbeing situated above and extending over part of said movable grate, andmeans for adjusting said plates to and from the grate.

In the accompanying drawings, Figure l is a top plan view of a fire-boxprovided with my improved means for supporting the firebrick lining.Fig. 2 is a vertical transverse section of the same. Fig. 3 is adetached perspective view of my preferred construction of thefire-brick-lining supporter. Fig. 4 is a plan View of the blank fromwhich said supporteris formed. Fig. 5 is a face view of a modificationof my invention, and Fig. Fig. 6 is an end view of the same.

Similar letters of reference indicate corresponding parts.

0 represents the fire box of a stove or range, and D is the grate, whichmay be of any suitable shape. The inner walls of the fire-box above thegrate are protected by lirebrick linings, as indicated by dotted lines 1l in Fig. 2 of the drawings.

In some fire-boxes the front is protected by a water-chamber coveringthe front wall of the fire-box and dispensing with the fire-brick lin-5o ing thereat.. In cases where the fire-box is deprived of suchwater-chamber the fire-brick linings Z Z are applied to the front aswell as to the back of the fire-box, as shown in Fig. 2 of the drawings.These linings have heretofore been supported upon a horizontal framewhich was supported upon lugs on the front and rear walls of thefire-box and upon the tops of the grate-hanger boxes at a. In the use ofsuch supporting-frame it has been found that it is liable to sag ontothe grate and prevent the same from turning. To obviate this defect, Iemploy is provided at its base with a ledge c, constituting the seat ofthe fire-brick lining. This plate, with its ledge, I preferably form ofa wrought-iron blank B, (shown in Fig. 4 of the drawings,) which blank Ibend along the dotted line 0 at the requisite angle to form the ledge 0.(Shown in Fig. 3 of the drawings.)

To guard more efiectually against the sagging of the ledge c, I form thecentral portion of the plate 12 with a vertical extension, as shown atb, and perforate said extension, as shown at e, for the reception ofbolts or other suitable devices for fastening said plate to the wall ofthe fire-box. Said perforations may be made to secure the plate I) inproper position to carry the ledge o in its requisite proximity'to thesubjacent grate D, as shown in Fig. 2 of the drawings. Consequently thesaid plate, with its ledge, is adapted to be applied to fire-boxes ofvarying depths.

The aforesaid construction dispenses with the usual false back of thefire-box. however, limit myself to the construction shown in Fig. 3 ofthe drawings,inasinuch as myimproved fire-brick supporter may beconstructed as shown in Figs. 5 and 6 of the drawings, in which theledge c is formed separate from the plate I) and is secured thereto byangle-irons f f, riveted to said parts. this case the plate I) isreinforced by a hanger or vertically-elongated plate h, formed at itsbase with a horizontal ofiset 77., upon which the center of the ledge crests. This hanger and its offset are fastened, respectively, to theplate Z) and to the ledge c by means of rivets 'i z'.

The hanger is perforated, as shown at t t,
